Hi All, I’m currently using the ESP32 WROOM-U32 module which only has up to 16MBytes flash on the module. The datasheet for the ESP32 basically says that this is the max. However, I see in the API section of this website that there is a VFS driver to support the Winbond W25N01 and W25M02 chips, which are much bigger than 16MBytes.
If the driver works I could disable the module’s flash and add one of these chips, but I’m confused. If the MPU has memory mapping issues beyond 16MBytes how can this work? Is it tested? I currently want to replace an SPI connected SD card.
Thanks very much.
